We just experienced our third episode in three months of the security system locking out the starter. The computer recognizes the keys and adjusts the wheel and seat, but when we turn the key, no starter. There is an initial single click as if the battery is weak (which it isn't), and then nothing. When the key is released the computer starts issuing messages, e.g., check suspension, check security system, check headlamps, etc. My understanding is that those messages and codes are the security system creating chaos to deter theft.
Now what's strange (at least to me) is that there seems to be some kind of "self cure". The first time, we replaced the battery and positive post as it showed some corrosion. It worked fine. The second time, after trying the key several times and then leaving it for an hour while waiting for a tow truck, it started when the gear shift was moved from park to neutral. We thought maybe the problem was in the shift indicator?! The third time, we tried all our tricks by disconnecting the battery for several minutes, moving the shift lever from park to neutral and back, etc. After leaving it overnight, we had it flat bedded 35 miles to the dealer. After rolling it off, the service tech got in and it started right up. It then showed EVERY code except the ABS system.
The dealer says he suspects either the IPcluster or the ECM or both, but isn't really sure and can't guarantee a fix even after these are replaced. (The car has 64K miles). He claims they've checked the grounds and they seem "fine". So...any advice or suggestions other than to spend $1400 for the dealer's "fix"? Thanks!
